Some
peculiarities and results of ecological monitoring of the Caspian Sea coastal
zone and the mouth zone of the river Volga are discussed. A shipboard laser
spectrometer, elaborated by the authors, was included in the measuring complex
of the new ecological patrol vessel Russia
belonging to the Foreign Economic Association Zarubezhgeologia of the Ministry of Natural Resources of the
Russian Federation. Emission spectra with laser excitation at 532 and 266 nm
were registered both in motion of the ship and at stations, containing the Mie
scattering line, the Raman scattering (RS) band from water, the fluorescence
bands of dissolved organic matter (DOM), oil pollution (OP) and phytoplankton. For
this specific aquatic region special attention was given to the determination
of OP concentrations from the spectra. It is shown that the direct fluorescence
method allows the OP concentration to be determined without sample preparation
in all types of water down to 10 mg/l using a new water-soluble standard. A very
high variability of the intensity of the above-mentioned spectral bands was
detected in the investigated area. The results demonstrate the practical
application of the methods and tools of laser spectroscopy to the ecological
monitoring of aquatic systems with complex structures and dynamics.
